[GRASS-user] Can I turn off compression

[Ken Mankoff]

Hm. Answer: No

I just did:

export GRASS_COMPRESSOR=none

And then get this error message:

WARNING: No compression is not supported for GRASS raster maps, using default ZLIB

Seems like a shame to not have this as an option. I'll try speeding it up by tweaking the compression method and amount.

  -k.
